AMF seems to require some additional (may be even closed-source/proprietary)
components from amdgpu-pro ?
Yes, amf is part of AMD's proprietary drivers, namely amdgpu-pro.
Other proprietary parts (OpenCL) have been put inside ROCm which is
open, but I don't think they will do that for amf.
Some time ago I had tried to create an x265-amf rendering profile, but
it didn't work. Now I don't have any amgpu-pro parts and can't try
anymore....
I expect you are right above, as I have no own experience yet with the
new AV1 encoding using GPU HWA.
The opensource Mesa 23.3 seems to be an option in any case

The ArchLinux wiki "Hardware video acceleration" is a good overview for
Linux options and driver installations for Intel, NVIDIA, AMD/ATI

* Advanced Media Framework (AMF) is an open source framework which
allows "Optimal" access to AMD GPUs for multimedia processing using
the AMDGPU PRO Stack, Developed by AMD.
* AMDGPU PRO proprietary driver is built on top of AMDGPU driver and
supports both VA-API and VDPAU in addition to AMF.
* NVAMDGPU PRO proprietary driver is built on top of AMDGPU driver and
supports both VA-API and VDPAU in addition to AMF. DEC/NVENC -
NVIDIA's proprietary APIs for hardware video acceleration, used by
NVIDIA GPUs from Fermi onwards.
The "av1_amf" encoder is included among the AV1 Encoders on my FFmpeg
6.0.1 currently on Tumbleweed-Slowroll.
Also the FFmpeg "AV1 Video Encoding Guide" has a section "AMD AMF AV1"
using the av1_amf encoder
